Problems solved by technology

That is, in a cuff having a single air bag that also serves both the blood pumping air bag and the pulse wave detection air bag, it is necessary to wrap the air bag around the entire circumference including the site to be measured. The cuff, so the placement of a hard core material in the air bag will significantly hinder the installation of the cuff.
[0014] In addition, even if the above technology can prevent the bending of the small air bag for pulse wave detection, it cannot suppress the occurrence of large wrinkles and bends in the large air bag for blood exsanguination that occurs during pressure supply.
Therefore, when large wrinkles and bends are locally produced in the blood-expelling air bag, the measured site cannot be uniformly pressed in the entire range, resulting in a decline in the hemostatic performance.
Therefore, there is still a problem that the measurement accuracy of the blood pressure value is lowered.

Abstract

The invention provides a cuff for a blood pressure monitor which is wound around a measurement site of the living body, and includes an air bag having an inflated / deflated space formed therein by melting and bonding rims of an outer wall portion and an inner wall portion together. The air bag contains a band-shaped connecting portion, which has ends respectively attached to one end and the other end of the air bag in its winding direction around the living body, so as to extend substantially continuously from the one end to the other end of the air bag. The band-shaped connecting portion is arranged inside the inflated / deflated space of the air bag. With this configuration, a cuff for a blood pressure monitor permitting uniform inflation of the air bag over the entire region when the pressurized air is introduced therein is obtained.

Description

technical field [0001] The present invention relates to a cuff for a sphygmomanometer that is wound around a body part to be measured, such as a wrist or an upper arm, when measuring blood pressure. Background technique [0002] Usually, when blood pressure is measured, a cuff containing a fluid bag for compressing an artery inside the body is wrapped around the body surface of the body, and the wrapped fluid bag is expanded and contracted to detect the blood pressure in the artery. The generated arterial pressure pulse wave is used to measure the blood pressure value. Here, the so-called cuff refers to a belt-shaped structure having a lumen, which can be wound around a part of the body, and is used for measuring arterial pressure of the upper and lower limbs by injecting fluid such as gas or liquid into the lumen. Therefore, a cuff is a term that includes a fluid bag and a winding member for wrapping the fluid bag around the body. In particular, a cuff that is wound around...
